Properties

AllowDeselect

Gets or sets a value indicating whether clicking the already-selected radio clears the selection. Only takes effect when Required is false (Required wins).

public bool AllowDeselect { get; set; }

Property Value

bool

HasSelection

Gets a value indicating whether a value is currently selected.

public bool HasSelection { get; }

Property Value

bool

Members

Gets the radios registered to this group, in registration order.

public IReadOnlyList<RadioControl<T>> Members { get; }

Property Value

IReadOnlyList<RadioControl<T>>

Required

Gets or sets a value indicating whether the group cannot return to "none" once a value is selected (deselect and Clear() become no-ops while a selection exists). Does NOT force an initial selection.

public bool Required { get; set; }

Property Value

bool

SelectedRadio

Gets the member whose Value equals the current selection, or null.

public RadioControl<T>? SelectedRadio { get; }

Property Value

RadioControl<T>

SelectedValue

Gets or sets the currently selected value, or default(T)/none when nothing is selected. Setting it updates the selection (honoring Required), repaints affected members, and fires SelectionChanged once.

public T? SelectedValue { get; set; }

Property Value

T

Methods

Clear()

Clears the selection to none. No-op when Required is true and a selection exists.

public void Clear()

Events

SelectionChanged

Occurs when the selected value changes.

public event EventHandler<T?>? SelectionChanged

Event Type

EventHandler<T>

SelectionChangedAsync

Async counterpart of SelectionChanged.

public event AsyncEventHandler<T?>? SelectionChangedAsync

Event Type

AsyncEventHandler<T>
